Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Cells are the basic building blocks of life. For cells to survive and function normally‚ fluids and electrolytes must keep a harmonious balance. The human body is composed of approximately 60% electrolyte-containing water‚ in which it is the kidneys’ job to regulate. Any loss of water should be matched with a consumption of water on a daily basis to ensure cells receive a constant balance of fluids. Water from our bodies comes from foods and liquids. Water loss is mostly through urine and

It can also be determined from Table 1 that there were 2 solutions with strong electrolytes‚ 2 with weak‚ and 2 with no electrolytes. The two solutions with strong electrolytes were NaCl and MgCl2. Ammonia and acetic acid had weak electrolytes.

In this chemistry science fair project‚ you will compare the electrolytes present in a sports drink with those in orange juice to find out which drink has more to replace the ones you lose as you’re working out or playing sports. When you are finished‚ you might even want to make your own sports drink! Objective To investigate whether or not a sports drink provides more electrolytes than orange juice. Introduction

(SOFCs) operating at intermediate temperatures the adjacency of the state-of-the-art yttria-stabilized zirconia (YSZ) electrolyte with ceria-based materials to both anodic and cathodic sides is regarded as crucial for the effectiveness of the cell. Solid-state reaction‚ however‚ and interdiffusion phenomena between YSZ and ceria-based materials can cause degradation of the electrolyte. When a gadolinia-doped-ceria (GDC) layer is used to protect YSZ against interaction with Co-containing cathodes‚ an

imbalance of electrolytes at any point of their lives‚ it could be deadly. When someone takes a grain of salt and puts it into a glass of water‚ the salt dissolves into the glass. Despite the fact the salt is dissolved in the glass‚ it is actually breaking into component ions‚ this creates an electrically conductive solution. That is what electrolytes are‚ they are any fluid that conducts electricity. In the human body‚ there is several very known electrolytes and every one of those electrolytes serve an

Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq) b. Aqueous NaCl—Sodium Chloride

Ions existing in a liquid state are electrolytes. An electrolyte is any compound that‚ in solution‚ conducts electricity and is decomposed or electrolyzed by the electricity. Electrolytes play an essential role in the function of the human body. As ions
